Be it known that I, Invmc F. WEBB, a citizen of the United States,residing at Elizabeth, in the county of Union and State of New Jersey,have invented. certain new and useful Improvements in Filled-Sack- ISewing Machines,of which the following is a specification, referencebeing'had therein to the accompanyin drawings.

This invention re ates to improvements in filled sack sewing apparatusincluding a sack conveyor and a sewing mechanism, and

has for an object to rovide actuatingmeans for the sewing mec anismcontrolled independently of the actuating means for the sack-conveyer. c

The invention has for a further object to provide a separate control foreach of said actuating mechanisms.

Another objectof this invention is to provide actuating mechanism forthe sack conveyer permitting the required adjust? ments of the conve er.a 1

Other objects o this invention will be apparent from the followingdescription and claims. r y

In its preferred embodiment, the present improvement comprises a filledsack sewin apparatus havin asuitable frame-wor supporting a verticallyadjustable sack-conveyor and an overhanging sewing head. The actuatingmechanism for the sack-oonveyer consists of an electric motor, supportedby a bracket secured to the conveyer-frame and having drivingconnections with the loose pulley of a power transmitter. This powertransmitter is controlled by a treadle in a manner permitting verticaladjustment of the transmitter without afiecting the position of thetreadle. The sewing machine is driven from a motor secured to the framework "of the apparatus through the intermediary tof a power transmitteralso secured to the frame-work and adapted to be controlled by a treadleindependent of the tread is controlling the o ration of the conveyor.

Theinvention wil beunderstood by reference to the accompanying drawings,in

' i which Figure 1 is a Wow in elevation of the j. Specification ofLetters Patent. Patented Dec 27, 1921 Application filed January 24,1913. Serial No. 213,509.

Fig. 5 is a sectional view ofthe right-hand conveyerframe supporting-bracket as viewed from Fig. 1. Pig. 6 is a sectional view of the left hand conveyer-framesupporting-bracket as viewed from Fig. 1. Fig. 7 is a sectional view onthe line AA of Fig. 6. Fig. 8 is a detail view of theconveyer-actuating-motor su porting-bracket.

eferring to the drawings, the filled sack sewing apparatus comprises abase 1 from which rise the upwardly projecting standards 2 and 3,supporting the table 4. Se-

cured to the table 4 is a bracket 5 carrying the overhanging sewingmachine 6 of well known construction. The driving pulley '7 of thesewing machine is driven by a belt 8 passing over the adjustableidler-pulleys 921ml 10 mounted on the supporting post 11 secured to abase 12 suitably positioned upon the table 4. Beyond the idler pulleys,the belt 8 passes through suitable apertures in the table 4 and aroundthe driving pulley 14 of a power transmitter 15 of a well-known type andsupported by a bracket 16, secured to the underside of the table 4. Theloose pulley 17 of the power transmitter is adapted, to be clutched toorunclutched from the driving pulley by means of the usual start ingandbrake-lever 18, connected by means of the relatively adjustable rods 19and 20 wit-h a lateral arm 21 secured to a rock-shaft 22. Therock-shaft'22 is supported in bear ings 23 and 24, secured to the base 1of the apparatus and is acted upon by a. spring 25' to normally hold ina substantially vertical position the treadle 26 secured upon the rockshaft 22 by means of the collar 27. The loose pulley 17 of the powertransmitter 15 is constantly driven by means of a belt 28 from theelectric motor 29 supported by the base 1.

Positioned below the sewing machine 6 is the conveyer comprising anendless carrier-belt 30 passing around the driving pulley 31 and guidingpulley 32. These pulleys of the conveyer-frame 33 for a purposehereinafter described. The bracket 35 is formed with elongated slots, as39, entered by pins, as 40, screw-threaded into the conveyerframe 33resting upon the bracket. Each of the brackets issecured by bolts, asl1, to nuts, as 42, to permit sliding movement upon the standards 2 and3. Threaded into the nuts 42 are vertical screw-rods, as 43, supportedin bearings, as 44, and carrying bevel-gears, 45, in mesh with similargears, as i6, upon horizontal shafts, as 4-7, journaled in bearings, asa8, on the under side of the table 4- and carrying crank-handles, as 49.By simultaneously manipulating the handles 49, it is evident that anydesired vertical adjustment of the conveyer may be obtained. hen one ofthe crankhandles is manipulated slightly faster than the other, theconveyer-frame 33 swings on the pivot-pin 37, which is permitted by theprovision of the slots 39 in the bracket 35.

The driving pulley 31 for the carrier-belt is mounted on the shaft 50,coupled by means of the ribbed-washer, 51 with the power transmittingshaft 52 rotatively supported upon a bracket 53secured by bolts, as541-, to the conveyer-frame 33.. The-power transmitter, as usual,includes a continuously driven loose pulley 55 and a-driving pulley 56adapted to be forcedinto driving engagement with the pulley 55 by meansof a startingandbrake-lever 57. The pulley 56 is keyed to the drivingmember 58 of a planetary gearingand carrying a pair of double spur-gears59 and 60 mounted to rotate upon their own axes. The gears 59 mesh withthe stationary spur-gear'6l carried by the shaft 62, upon which theloose pulley 55 is mounted to rotate and which shaft is rigidly boltedto the bracketextenison 63 of the bracket 53. The spur-gears 60 have asmaller number of teeth than the spur-gears 59 and mesh with thespur-gear 64 keyed to the shaft 52. By means of this construction, thedesired driving ratio of the pulley 56 relatively to the shaft 52 may beobtained.

The loose pulley 55 is constantly rotated by a belt 65 driven by anelectric motor 66 supported by a bracket 67 secured by bolts,

as 68, to the conveyer-frame- 33. -Consequently the actuating means forthe carrier belt 30 maintains a definite relative position with regardto the conveyer-frame 33 in spite of any adjustments of theconveyerframe. V

To the startingand brake-lever 57 is-secured one end of a spring 69 ofwhich the other end is secured to a post 70 projecting from thebracket-extension 63, this spring acting toholdthe lever 57 in contactwith the vertical rod 71 secured by rods 72 to the vertical fulcrum-rod73, supported at its upper end in a bearing 74 secured to the under sideof the table 4;, and at its lower end in a bearing 75 on the base 1. Therod 7]. is connected by means of a longitudinally adjustable link 75'with a crank-arm 76 secured to a treadle actuated rock-shaft 77 mountedin bearings 78 and 79 on the base 1. A foot-plate or treadle 8O securedto the rock-shaft and is normally held in raised position by a spring81, the action of the spring being limited by a stop-pin 82 so cured tothe shaft and adapted to bear upon the base 1. By pressing downward uponthe treadle 80, the consequent actuation of the rock-shaft causes therod 71 to swing about its fulcrum and thereby act upon the lever 57 toforce the driving pulley 56 into frictional contact with the constantlyrotated pulley 55. The treadle connections described are entirelyindependent of the mechanism for actuating the sewing machine and permitvertical adjustment of the conveyorframe 33 and its actuating mechanism.
